A below-knee amputation, also known as a transtibial amputation, is often necessitated due to trauma, infection, or vascular conditions associated with diabetes. The process of receiving a below-knee prosthesis begins with a thorough assessment of the amputee’s requirements, followed by accurate measurement of the residual limb, ensuring a comfortable fit for the amputated leg.

A prosthetist then creates a personalized definitive prosthesis, which is adjusted to ensure comfort and effectiveness.

The Journey from Amputation to Prosthesis

Transitioning from amputation to prosthesis involves a joint effort from the patient, the prosthetist, and the rehabilitation team. It begins with the initial fitting of a diagnostic socket, which accommodates changes in the shape and size of the residual limb.

Next comes the shift from the temporary prosthesis to the permanent one, which provides more stability.

Types of Below Knee Prostheses

There are various types of below-knee prostheses available, each designed to cater to individual needs and lifestyles. Models with an active vacuum system and those with a silicone liner pin system are the most widely preferred designs. They are known for their popularity in the market. These prostheses include a personalized socket that is shaped to fit the patient’s limb perfectly.

Importance of a Proper Fit

The fit of a prosthetic leg plays a fundamental role in its usefulness. It directly impacts comfort, mobility, and the overall success of the user. The diagnostic socket serves as a transparent, plastic socket utilized to assess the proper fit of the prosthetic socket and pinpoint any areas requiring modification. The prosthetist can be forced to create multiple diagnostic sockets before finding the one that fits perfectly on the patients leg. In the immediate time after amputation, the patients leg changes shape and form several times so changing sockets mulptile times over the first 1-2 years is very common.

Essential Components of a Below Knee Prosthetic Leg

A below-knee prosthetic leg consists of four key components – the socket, the pylon, the foot, and the suspension system, all working together to mimic the function of a natural knee joint.

The Socket: Your Connection to Comfort

The socket connects the residual limb to the prosthetic leg, providing a vital base for the user’s comfort and stability. It is typically constructed using carbon with a flexible brim, ensuring a perfect fit.

Pylon and Foot: Supporting Your Steps

The pylon, often made of aluminum, stainless steel, or titanium, provides structural support for the leg.

The foot, on the other hand, offers a base and mimics the function of a natural foot, supporting various activities, including walking and running.

Suspension Systems: Keeping Your Prosthesis Secure

The suspension system secures the prosthesis to the residual limb, providing stability and preventing excessive movement. This system ensures that the prosthesis remains securely attached, even during vigorous activities.

Rehabilitation with a Below Knee Prosthetic Leg

Rehabilitation is a significant stage in the journey towards adapting to a below-knee prosthetic leg. It involves physical therapy, gait training, and overcoming challenges such as pain management and skin irritation.

Gait Training: Learning to Walk Again

Gait training helps you relearn walking with your new prosthetic leg. It instructs the individual on the correct way to walk, ensuring correct heel strikes of the non-prosthetic limb, and providing verbal and tactile cues to improve prosthetic limb training. Training is even more important for bilateral amputees where one would have no human leg/foot.

Overcoming Challenges: Pain Management and Skin Irritation

Pain and skin irritation are common challenges faced during the rehabilitation of a prosthetic leg. Pain management techniques include:

  • Epidural analgesia for postoperative pain relief
  • Wearing an elastic stump sock
  • Stump massage
  • Use of cold packs

For skin irritation, maintaining good stump hygiene, wearing loose clothing, and using moisture-wicking fabrics can be beneficial.

Long-term Care and Adjustments

As the residual limb evolves over time, long-term care and modifications become indispensable. Regular check-ups and adjustments are vital for ensuring the appropriate fit and comfort of the prosthesis.

Adapting to Life with a Below Knee Prosthesis

Adapting to life with a below-knee prosthesis involves mastering everyday activities, participating in sports, and coping with the psychological aspects of limb loss, all while learning to navigate daily life without the use of a real leg.

Everyday Activities: Home, Work, and Beyond

Adapting to everyday activities with a prosthetic leg may require adjustments at home and work. This could include repurposing household items or making modifications to the home environment to enhance mobility and accessibility.

Engaging in Sports and Recreational Activities

With a below-knee prosthesis, you can engage in various sports and recreational activities such as cycling, wakeboarding, and horseback riding. The use of a prosthesis can be adapted to suit these activities, and the choice of prosthetic components may require customization for activities involving water.

Psychological Aspects: Coping with Limb Loss

Coping with the psychological aspects of limb loss is an integral part of the overall adaptation process. Counseling can aid in coping with a below-knee amputation by facilitating acceptance of body image, alleviating distress, and averting psychological abnormalities.

Personalizing Your Prosthetic Experience

Tailoring your prosthetic experience can enhance the comfort and satisfaction during the adaptation process. This can be achieved through cosmetic coverings, technological innovations, and working closely with your prosthetist.
